Observations on strongyloidiasis in Queensland aboriginal communities

|February 1, 1993
Summary
Strongyloidiasis infections are prevalent in many Aboriginal communities in Queensland, particularly among children. Targeted treatment with thiabendazole shows promise for reducing and potentially eradicating this parasitic nematode.
Area of Science:
- Tropical medicine
- Parasitology
- Public health
Background:
- Strongyloides stercoralis is a parasitic nematode with significant public health implications.
- Understanding its prevalence and distribution is crucial for effective control strategies.
Purpose of the Study:
- To determine the prevalence and geographical distribution of Strongyloides stercoralis infections.
- To investigate infection patterns in Aboriginal and Torres Strait Islander communities in Queensland.
Main Methods:
- Retrospective analysis of 20-year (1972-1991) health data from Queensland's Aboriginal Health Programme (AHP).
- Microscopic examination of preserved fecal specimens.
- Comparison of findings with published annual reports.
Main Results:
- An overall infection prevalence of 1.97% was detected in 32,145 fecal samples.
- Infections were identified in 52 out of 122 communities, with higher prevalence in northern regions.
- Peak prevalence reached 27.5% in children in Doomadgee; treatment with thiabendazole at Gununa reduced prevalence from 26.2% to below 7%.
Conclusions:
- Strongyloidiasis is endemic in many Aboriginal communities in northeastern Australia, with children as primary reservoirs.
- Improved sanitation and hygiene are essential.
- Selective treatment of infected children with thiabendazole could significantly reduce or eradicate the infection.
